Add Space Between Bullet and List Item

Is it possible to increase the space between a bullet (or number) and the list item ("li") in Squarespace?  Other online sources suggest the "padding-left" property can create space, but it has no effect for me in Squarespace.  Here is my page header code injection:

<style>
    #block-1c678d9fa895b621a5d2 
  ol li {
     padding-left: 20px;
     margin-bottom: 1.5em;
  }
</style>

The "margin-bottom" property works fine, but not the "padding-left."

Many thanks in advance!
